LATHE-FEED.

SPECIFICATION forming part of Letters Patent No. 701,564, dated June 3,1902. Application filed nmhiaieo'z. Serial lilo-98,065. (No model.)

T all whom it rnaty concern:

Be it known that we, BENGT M. W. HANSON, a citizen of Sweden, andFREDERICK W. Gon- DON, a citizen of the United States, both residing atHartford, Hartford county, Connecticut, have invented certain new andusefulImprovements in Lathe-Feeds, of which the following is aspecification. This invention pertainin g to improvements to inlathe-feeds will be readily understood from the following description,taken in connection With the accompanying drawings, in which- Figure 1is an end elevation of a lathe provided with feed mechanism exemplifyingour 1 5 present invention, the change gears being omitted and part ofthe quadrant being broken away; Fig. 2, a vertical transverse section ofthe main parts of the mechanism; Fig. 3, a front elevation of themain'p'arts of the'mechzo anism, certain details appearing in verticalsection; and Fig. 4, a plan of the-tumbler.

In the drawings, 1 indicates the bed'of the lathe; 2, the head-stock; 3,the arbor {4,- the: lead-screw; 5, the change-gearstud; 6,'thearbor-feed pinion; 7, the driven. gear of the stud; 8, thereversing-gears in the head-stock, I

all the parts thus far referred to being constructed as usual exceptthat while the pro? I jecting end of change-gear stud'5 is adapted toreceive the ordinary change-gears such is not the case with the end ofthe lead-screw l;

0, a long pinion supported by the lathe-bed parallel with the lead-screw10, the head end of this pinion, the same being adapted to receive thechange-gear in line with a changegear on change-gear stud 5; 11, achange-gear thus mounted on the end of the long pinion;

12, an ordinary quadrantfiSocalled, for ad-- justably carrying suchintermediate gear as may be employed betweenchange-gearsvon thechange-gear stud and the end of the long pinion; 13, a longitudinalguideway parallel with long pinion 9. and extending its whole length andhaving the form of a rocking frame; 14:, arms at the end of thisguideway extending inwardly toward the journals of the long pinion; 15,hearings on these arms, with their common axis coincident with the axisof long pinion 9, the guideway thus rocking and the carriage to traversethe guideway; 23,

transversely upon the axis of the long pinion; 16, a carriage arrangedto slide lengthwise in guideway 13; 17, an idle gearjournaled in carriage 16 and constantly meshing with the long pinion regardless of theposition of the carriage in the guideway; 18, a series of gears ofdiverse size fast on the lead-screw, a longitudinal adjustment of thecarriage 16 in conjunction with the angular adjustment of the guidewaypermitting idle gear 17 to be put into gear with any selected one ofgears 18; 19,- a finger-latch pivotedto the guideway; 20, a fixedsegment of detent-hole's adapted to be selectively engaged by latch 19and hold the guideway fixedly in adjustedangular position after idlegear 17 is properly engaged with one of gears 18; 21, a pinion journaledon carriage 16; 22, a longitudinal rack carried by guideway 13 andengagedby pinion 21, so that the turning of the pinion will cause it acrank fast with pinion 21; 24:, a detent-pin carriedlby this crank; 25,two longitudinal series of detent holes in the gu'idew'a'y, adapted. tobe selectively engaged-by detent-pin 24, and 26 a casing secured againstthe front of the lathe-bed near its head end and serving toinc'l osegears 18 and furnish bearings for the lead-screw and long pinion and tosupport the guideway.

The usualchange-gears give motion to the long pinion from change-gearstud 5, and the change-gears as interchangeable elements need not beemployed i the'variety of gears in group 18 is sufficient to satisfy thespeed ratios desired for the lead-screw. By releasing detect-pin 24: andturning crank 23 and putting the detent-pin to a properly-selected oneof de'tent-hol'es' 2-5" the carriage can be traversed along in the.guideway and idle gear 17 brought to the plane of any selected one of"gears 18. By releasing latch 19 and then rocking the guideway and thenengaging the latch with the properone' of its detent-holes 20 the idlepinionc'an be brought properly into gear. withthat oneof gears 18 withwhich it has been brought .into line.

While the device has been illustrated and described as a lathe-feed, itis nevertheless to be understood, as will be obvious, that the inventionwill well lend itself to numerous other situations.

\Ve claim as our invention 1. The combination, substantially as setforth, of a shaft provided with a series of gears of diverse sizes, apinion disposed parallel with said shaft and having a length equal tothat of said series of gears, aguideway disposed parallel to said pinionand arranged to rock upon the axis of the pinion, a carriage mounted toslide in the guideway, a gear mounted in the carriage and engaging saidlong pinion and adapted to engage any of said series of gears, and meansfor securing the rocking guideway and the carriage in position.

2. The combination, substantially as set forth, of a shaft provided witha series of gears of diverse sizes, a pinion disposed parallel with saidshaft and having a length equal to that of said series of gears, aguideway disposed parallel to said pinion and arranged to rock upon theaxis of the pinion, a carriage mounted to slide in the guideway, a gearmounted in the carriage and engaging said long pinion and adapted toengage any of said series of gears, gearing connecting the carriage andgnideway and serving to shift the carriage along the guideway, and meansfor securing the rocking guideway and the carriage in position.

3. The combination, substantially as set forth, of a shaft provided witha series of gears of diverse sizes, a pinion disposed parallel with saidshaft and havinga length equal to that of said series of gears, aguideway disposed parallel to said pinion and arranged to rock upon theaxis of the pinion, a carriage mounted to slide in the guideway, a gearmounted in the carriage and engaging said long pinion and adapted toengage any of said series of gears, a rack supported by the guideway, apinion journaled on the carriage and engaging the rack, a crank forturning the pinion, and means for locking the rocking guideway and thecarriage in adjusted position.

4. The combination, substantially as set gears of diverse sizes, apinion disposed parallel with said shaft and havinga length equal tothat of said series of gears, a guideway disposed parallel to saidpinion and arranged to rock upon the axis of the pinion, a carriagemounted to slide in the guideway, a gear mounted in the carriage andengaging said long pinion and adapted to engage any of said series ofgears, a rack supported by the guideway, a pinion journaled on thecarriage and engaging said rack, a crank for turning said pinion, adetentpin carried by said crank and adapted to engage selectivedetentholes in the guideway, and means for locking the rockingguidewayin adjusted position.

5. The combination, substantially as set forth, of a shaft provided witha series of gears of diverse sizes, a second shaft mounted paralleltherewith, a pinion upon said second shaft, a guideway disposed parallelwith and arranged to rock upon the axis of said second shaft, a carriagemounted to slide in said guideway, an idle gear mounted in said carriageand geared to said second shaft and adapted to engage any of the gearsof said series of gears, and means for locking said rocking guideway andthe carriage in adjusted position.
